P0D96 indicates that the voltage on the unlock control output is too low, which usually means the release line is shorted to ground or the actuator pulls an overcurrent as soon as it is energised in the release direction. To protect its driver, the module stops commanding, so the pin stays where it is. If it was latched, the plug remains captive until the emergency release is used; if it was already open, the car may refuse the next session because it can no longer trust the lock. No manufacturer publishes this code, so the explanation draws on CARB's monitoring logic for output components and on actuator patents in which a position sensor confirms each end stop (GM, US8936482B2). Compared with P0D95 the circuit is not broken but shorted; the opposite fault, a short to supply, is P0D97.

Likely causes

Unlock drive wire shorted to ground at a chafe point
Actuator seized, for example by ice or dirt, causing overcurrent
Moisture in the actuator connector
Unlock driver stage of the module defective

Symptoms

  • Charge plug cannot be unplugged after charging
  • Emergency release needed to free the cable
  • Next charging session refused
